Abstract (en)
[origin: WO9637908A1] A lighting unit according to the invention comprises an electrodeless low-pressure discharge lamp (10) and a supply (60) for the lamp. The lamp (10) is provided with a discharge vessel (20) with a radiation-transmitting enveloping portion (21) and a recessed portion (24). The discharge vessel (20) encloses a discharge space (27) in a gastight manner and contains an ionizable filling. The lamp (10) is in addition provided with a coil (30) positioned in the recessed portion (24) for generating a high-frequency magnetic field so as to maintain an electric discharge in the discharge space (27). The enveloping portion (21) of the discharge vessel (20) is provided with a radiation-transmitting, electrically conducting layer (22) at a surface facing the discharge space (27), which layer is electrically connected to a lead-through member (42) which issues to the exterior from the discharge vessel. The lead-through member is a metal tube (42) which forms at least a portion of a tubular projection (46, 42, 47). The discharge vessel (20) of the lighting unit according to the invention can be manufactured comparatively easily and can have a comparatively compact construction.
